UNITED STATES PATENT OFFICE GRIN BEARSE, OF HYANNIS, MASSACHUSETTS.

'IMPROVEMENT IN HAWSE-PIPE STOPPER.

Specification forming part of Letters Patent No. 104,101, dated June 14,1870.

To all whom it may concern:

Be it known that I, ORIN B. BEARsE, of

`Hyannis, in the county of Barnstable and State of Massachusetts, havein vented a Hawse- Pipe Stopper, of which the following is a full, iclear, and exact description, reference being had to the accompanyingdrawing, making part of this specification, in which- 4Figure 1 is aperspective View of my stopper applied to the hawse-pipe of a vessel.

Fig. 2 is a section through the center of the j same 5 Fig. 3, detail tobe referred to.

When a vessel is sailing in a rough sea with the hawse-pipe open, moreor less water is taken in at this point, the quantity being greater invessels of small tonnage, wherel the hawse-hole is near the water, as isparticularly the case with sloops, schooners, Svc., the cargo vouter endof each portion of the clasp being provided with a packing of rubber orother suitable elastic material, which prevents the water from enteringwhen the clasp is forced against the inner end of the hawse-pipe bymeans of a screw-clamp or other suitable device.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawing, A A are two semicylindrical blocks, surrounded bystraps or bands B B, hinged together at a.

The inner surfaces of the blocks A A are recessed out for the receptionof the links b of the chain to which the anchor on the cathead 7 issecured, the chain fitting the portions of the block so snugly that whenthey are closed down upon it they serve as a clasp, which is locked bymeans of a pin, c, thus holding the chain securely in place.

To the outer end of each ofthe blocks A A is secured a packing, d, ofrubber or other suitable elastic material, which fits closely around thelink which projects from the block, and thus prevents the entrance ofwater and consequent damage to the cargo when the stopper is pressedfirmly against the inner end of the hawse-pipe C by the device whichwill now be described.

c c are two studs projecting from the inside of the bulwark orplank-shear, one on each side of the hawse-pipe. To each stud is pivotedone end of a bent brace, E, through the center of which passes a screw,G, to the outer end of which is secured a disk, H, which is turned harddown upon the inner end of the stopper, thereby forein g the elasticpacking l tightly against the inner end ofthe hawse-pipe, andeffectually preventing the entrance ot' water. The inner end of thestopper is cutaway at f, so that the links may lie flush with its endsurface, and allow the disk H to lit snugly up against it.

When it is desired to cast anchor, the disk H is withdrawn by turningthe screw Gr, when the brace E may be swung up to, allow the stopper tobe opened by removing the pin c, when the chain is released and allowedto run out of the hawse-pipe.

The stopper, instead of being made in two pieces hinged together, may bemade in one piece, provided with an elastic packing, and be used inconnection with the screw-clamp for stopping the hawse-pipe when thechain is unbent.

Claim.

What I claim as my invention, and desire to secure by Letters Patent,is-

The within described stopper, consisting` essentially of the two blocksA A, which surround and hold the chain, in combination with an elasticpacking, d, and a screw-clamp, or equivalent device, for holding thestopper against the hawse-pipe, substantially as and for the purpose setforth.

fitness my hand this 17th day of March, A. D. 1870.
